WILLIAM MoLAUGHLIN, F GRAND RAPIDS, MICHIGAN, ASSIGNOR TO ALF ED D.RATHBONE, or GRAND R PIDs, M onIeAN,

GAS-BURNER.

SPECIFICATION forming part of 'Letters Patent No. 786,830, dated April11, 1905. i A lication filed April 25,1904. SerialNo. 204,746. I

To all whom, it may concern:

Be it known that I, WILLIAM MOLAUGHLIN,

a citizen of the United States, residing at GrandRapids, in the countyof Kent and State of Michigan, have invented certain new and usefulImprovements in Gas-Burners; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains'to make and usethe same.

My invention relates to improvements in gas-burners, andmoreparticularly to such burners adapted for heating purposes; and

its object is to provide means forsimultaneously adjusting the directionof the flamejets and the air-openings between the chambers to provideuniform combustion throughout, and to provide the device with variousnew and useful features hereinafter more fully described, andparticularly pointed out in the claims;

My invention consists, essentially, of a series of horizontalchambersmounted to rotate on their horizontal axes and provided with suitable jet-openings and also arranged in series one above the other, togetherwith a case in which the same are mounted, a stand pipe to supply gasunder pressure to separate nozzles, a nozz e and a mixing-tube for eachdistributing-chamber, and in various features of combination and.arrangement of parts, as will more fully appear by reference to theaccompanying drawings, in which,

Figure 1 is a front elevation of a device embodying my invention withparts broken away to showthe construction; Fig. 2, a ver-' tical sectionof the same on the line 2 2 of Fig. 1, and Fig. 3 an enlarged transversesection of one of the distributing-chambers.

Like letters refer to lIke parts in all of the figures. I

A represents a suitable stand-pipe to supply gas under pressure; B, aseries of separate and independently-operative nozzles to discharge thegas from the stand-pi e to the mixin'g-tubesC, in which tubes air 1smingled with the gas and the mixture projected into eachdistributing-chamber D equally and independently of the other chambers.Said chambers are preferably lozenge-shaped in cross-section, asindicated, and journaled in a suitable caseconsisting of side platesHand I and a back plate J, connecting the plates H and I and inclinedsomewhat toward the front at-the top, and thence curved forward, as atJ, to a point above the rear part of the upper distributing-chamber, andthence extended forward and upward in a plane substantially parallelwith the front surfaces of the chambers, as at J. The mixing-tubes Cproject through the plate I a short distance,

and the respective distributing-chambers D are journaled thereon, asshown in Fig. 1. The opposite ends of these chambers are j ournaled, asat F, whereby eachchamber may be rotated about its longitudinal axis toadjust the direction of the flames projected from suitable openings D inthe upper side near the front angle of the said chamber. These chambersare each formed in two parts divided at opposite angles, preferably theacute angles L L, and these two parts secured by suitable boltsor rivetsE, whereby the same may be readily cast without cores and readilycleaned on the inside.

The front of each distributing-chamber D and also the like inclinedupper part J of the back plate are preferably coated with asbestos orother suitable refractory and incandescent material,-as indicated at K.By adjusting the respective distributing-chambers D about theirhorizontal axes the direction of the flames projected from the opening Gcan be varied at pleasure to impinge more directly upon the asbestos Kor to be projected forward from the front of the device, as occasion mayrequire. Air passes upward between the distributing-chambers and theback J and'impinges upon the lower side of the respective chambers andis deflected forward between the same and upon the jets of flame, andthus supplies the same with additional air to insure more perfectcombustion. By rotating these distributing-chambers theairpassa e andthe direction of the air-currents, as wel as the direction of theflames, are also varied at pleasure.

The device may be utilized in a variety of Ways, and more especially toinsert in open fireplaces as grates and in conjunction with a mantle, orthey may be, made portable and attached by any suitable means to anyconvenient gas-supply.

By supplying each distributing-chamber with a separate et andmixing-chamber I am also able to provide uniform distribution of thecombustible mixture therein, and thus secure uniform jets of flame fromthe various series of openin s D.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. .The combination of a stand-pipe, a series of separate andindependently-operative nozzles and mixing-tubes attached tothestand-pipe, and a series of distributing-chambers spaced apart andjournaled on the respective mixing-tubes, and also supported by saidtubes, each of said chambers having a forwardly-projecting upper angleprovided with jet-openings and a rearwardly-projectin lower angleadjacent to the next chamber below and adjustable relative thereto.-

2. The combination of a stand-pipe, a series of separate andindependently-operative nozzles and mixing-tubes attached to thestand-pipe, a series of distributingchambers spaced apart and journaledon the respective mixing-tubes, and also supported thereby, each of saidchambers being lozenge shaped in cross-section and having aforwardly-projecting upper angle provided with jet-openlugs andadjustable relative to the forward surface of the next chamber above,each chamber also having a rearwardly-projecting lower angle adjustablerelative to the next chamber below, and a case having a back plateextending back of said chambers and thence forward and above the upperchamber and thence at an inclination forward and upward above the upperchamber, and in a pl an 0 parallel with the front side of said chamber.

3. The combination of a standpipe, a series of nozzles and mixing-tubesattached thereto, a stove-casing, a series of longitu dinally-divideddistributing-chambers, each having its rear portion ournaled on arespective mixing-tube at one end and supported thereby, said rearportion also being journaled in the stove-casing at the other end, thefront portion being cast separately and attached to the rear portion.

In testimony whereof I allix my signature in presence of two witnesses.
